Does it also hold promises for us? I think a cross-platform standard in the
connectivity area would be very sweet... Running on all kinds of desktops
and our green buddies would rock, wouldn't it?

Admitted, but the news seems to be they not only made the code accessible,
but also the whole thing open source, or did I get this wrong? So if
there's development in Rendezvous stating for all kind of platforms, how
does MacOS's network stack impact e.g. a Windows, Linux or Newton user?

Well, making it public might amend some things... Hoepfully.

Hmh, wouldn't this wrappe be implementable in Waba?

Okay, you kung fu is better than my kung fu as concerns these matters, so I
take it this whole thing is of no value for us? I was hoping it could be
beneficial for DCL and the multiplatformability of DCL. But what do I know.
No offense meant, Paul et al!
