I remembered I played with florist many years ago.Its website
(http://
www.cs.fsu.edu/~baker/florist.html) indicates that the latest update
was in 2003. I still can find florist lib package at Ubuntu and
Debian.

If my memory serves me correct, there were a few distributed examples
(one of them was Sieve of Eratosthenes) that came with the florist
package. Can someone please verify that?

I am a little bit curious on this: Does Ada require PolyOrb etc to
support Annex E?
