Velvet puffin is a desktop app that lets you log-in to all of your instant messaging accounts all at once. It's a *really* version 1.0 app. *All* it does is log you in to several messaging systems at once and connect to friends on your different systems ... whcih is what Trillian and others did back when they were verison 1.0. So it won't replace my own version 3-plus IM aggregator, but it does do plenty of nifty 1.0 things that people will dig. Casual users might really enjoy it.
It's a flash application, so it's cross-platform, but don't try to get it to do too much fancy work without leaking memory. On the other hand, AOL, Yahoo and Google are so insistent on bundling their way onto your desktop, the memory footprint isn't all that big a nuisance in comparison. Honestly, the choice between velvet puffin's memory usage and a client that pushes flashing banner ads at me all the time ... I might take the memory hog.
Sure, I uninstalled it pretty quickly, in favor of Trillian which I already use ... but I don't think I'm typical of web users. Velvet Puffin is incredibly easy to install and use, and I think that's important.
Perhaps they'll be bought-out for parts. The cross-system log-in, by itself, is a valuable function. They also have a reasonably solid webcam broadcasting tool, thanks to flash. The ability to share photos and videos with other users rounds out its features nicely. These are pretty useful parts.
