Socialtext Partners with Dan Bricklin on wikiCalc is an interesting follow up to the Google Spreadsheet news. I made the prediction that Google’s going to (someday) sell a box that you can drop onto your company network that lets you do collaborative spreadsheets and document editing. Socialtext, it would appear, can do that for you now, and using open source software if you want to manage it yourself! Or, you can get hosted services or buy their hardware/software combo (just like the GOB I was talking about).
I had heard of Socialtext previously, but I wasn’t aware of the SynchroEdit connection and wikiCalc coming into the fold certainly makes things more interesting.
