Looking for online tools

When I was an online student (Master's in Education, University of Phoenix), one of the hardest things was switching from computer to computer. I might stumble across a great site while at work that I would want to include in a paper--that was sitting at home on my computer. I might need to work with my classmates on a project, when we weren't all in the same time zone (or continent). I might find I had an extra ten minutes before a meeting at another university, and want to do some research in their databases, but on a computer that wasn't mine and that I couldn't print from.

I'm sure that other online students have similar problems. So, I'm trying an experiment. With the proliferation of great online tools, I want to know if it's possible to do most research related functions online: notetaking, collaboration, writing, presentation, etc. They must be browser based, i.e. not require any downloads to use, and must be server-based, i.e. be accessible from any Internet connected computer. Ideally, they should be usable in multiple browsers, and at least editing/adding should be password protected. They should also be free or very reasonably priced (maybe $30 a year or less?) This is a Web 2.0 sort of thing.

I'm going to write this up as a "Toolkit" for online research that I am compiling, which will also include tips on searching databases and the open web, plus copyright and plagiarism information.

Here are some of the tools I've found so far:

• Writely -- an online word processor (I blogged about this one last week.)
  
• Num Sum -- an online spreadsheet (Haven't tried this yet, but it looks interesting.)
• eSnips -- a web note-taking tool (This does require a download and at this point only works with Internet Explorer. I also can't get the "snipping" part to work right now. However, the concept is perfect and it's an early beta, so it's still on the list for now.)
• Kiko Calendar -- online calendar with collaboration features
• WebNotes -- open notetaking (not password protected)
• OperaShow Generator -- an online generator for the Opera browser based presentation format (Specific to the Opera browser, but even in other browsers you get PowerPoint style organization, kind of like presentation notes. If you have CSS skills, you should be able to tweek this to be viewable in any browser that uses CSS, though you might lose some of the advanced functions.)
• Skype's conference calling abilities
• Jybe for co-browsing the web
  
• Conversate for online discussions
  
• Wikalong for annotating websites (Firefox extension, but usable in other browsers via Bookmarklets)
  
• bookmarking tools like del.icio.us and FURL for saving links and sometimes content
  
• blogs for notetaking and reflection (in some, you can make the entries private)
• bibliographic citation managers and formatters, like RefWorks (RefWorks requires a subscription, but it, or a similar service, is available at many colleges and universities.) Some bookmarking tools also do citation managing, like Connotea and CiteULike, which pull citation data from databases, and FURL, which exports in APA, MLA, Chicago, and CBE formats. RedLightGreen, the Research Library Group's online catalog (or, really, a book search engine) will save and format references in APA, Chicago, Harvard,MLA, and Turabian.
  
• Also, things that aren't meant for research use, but can be used that way. LibraryThing could keep a collection of books used for projects.
  

Anyone have anything else to add? Please don't send your favorite generic bookmarking tool or blog host. I know I've only scratched the surface of these tools, but I don't want to make a huge list of these tools that will be impossible to keep updated. If you have a huge list that you plan to keep updated, I'd wouldn't mind seeing that, or if there's a particular tool that does something unusual, like FURL's export in citation formats. (Remember that comment word verification has been turned on, so if that sort of thing makes it impossible or too annoying for you to comment, please contact me in another way.)

I would also be interested in hearing from developers on what you are planning, and from students (and instructors) on what you think is needed.
