I thought I'd never heard of it, but then Googled and
remembered that it was presented to us at the MS thing I went to a few months back. It actually looked like a pretty decent thing for non-programmers to bang together basic applications.
SFB: we don't, but if you get desperate shoot me a PM. We use VSS so I'm sure picking up LS would be a piece of cake for our guys, although I suspect it would cost you more than a dedicated LS team (although I'm sure you'd get a correspondingly better end product :)
