Why not just post what was shown at CeBIT? Or at least make it available to those frequent posters....at least allow those of us actually encouraging or cajoling you (and Ilia - whatever happened to him? and Roman) about all of the false promises in the past?
If you can't, I do NOT understand the reason....it's a beta. We're asking, in effect, to be beta testers. And, that is what was shown at CeBIT.
As far as why it took so long, for a small company, my guess would be that there was a greater revenue promise with the Comm Server product that with RAdmin, especially due to the free upgrade policy that was promised us 2.2 (and earlier) purchasers.
Then again, it could have been to give our prez a model to use when he invaded Iraq. See, guys, vaporware has many realtime applications, such as WMDs!!!
