I think Skype is nt a professional service to send business oportunity,
I am sure that this partner can implement an internal messaging service,
like a jabber server, with acces just for the partners, one that can be
audited and secured where theres a need to be secured. Or maybe an IM is
not the solution.

Gentlemen,
Iam part of a Brazilian Information Security consultancy focused on
the SMB market segment and we're facing sth new.

We're used to see some companies offering partnership transactions
through web apps but this time we're dealing with the obligation of
sheltering a new service.

Some backgound:
one of our customers has its network pretty restricted, following ISO
27001 and ISO 17799 that is to say, all of the services within their
network were carefully chosen and deployed.
Their network itself was meticulously designed.

Now,
one big partner they have is forcing them to install Skype in order to
keep'em up to receive new business opportunities.

Well,
Skype is against their policies.
I was asked about how hazardous this could be to their network and I
said:
"no, Skype is not ok because it lacks transparency concerning your
firewalls, bridges, proxies and etc."

Not to mention its port agile features.

But,
did not give one final word yet...

The network's stability is my team's responsibility.

What to do? Risk their efforts in obtaining ISO certification?
Guess we need to hear some other professionals.

Thank you,
any comment will be extremmely useful.
