Ok, i agree with this idea. I already have the same idea, and others too.
But, becouse the security is a potential problem, scalable solutions for me
is a operational problem. In the HUBs (NTEs in order of the project) we don't
have profissionals with knowledge about firewalls and manage it remotely is
very hard. Because of that, on the version 1 of the project, we are plan to
install only one ZEO Storage Server, behind a firewall.
I'm discussing about these problems at some time with the technical team of
PROCERGS, and where, with the help of the list members, I'm collect more
"mind views".
To solve the problem, I'm think in implement secutity authentication services
for ZEO. But, for that i will need help. Does anybody can help me with the
implementation ??? With this resource, logicaly I will restructure the
network topology in levels and my application too (but, this is not the real
problem). Without authentication, a multilevel arquiteture is very dificult
to administrate.
Thanks a lot.
PS: Sorry for my english. ;-)
