Default settings: connect to Gnutella+eDonkey & enable UPnP?

Hi folks,
IMHO, it would be nice if Shareaza connected to all networks by default, and also enabled UPnP to attempt to forward the port automagically.
This is based on my daily experience on IRC: the average users don't have a clue about different networks, they just want to type a file name and get it as fast as possible. So the usual result is that it doesn't work because of the NAT (or works very slowly, which is the same for the user), he pops in the channel, and we spend half an hour explaining him how to configure Shareaza. When everything works fine they're really delighted.
Given the fact that Shareaza lacks advanced features like DHT networks, What's new searches on Gnutella, SecureID on eDonkey and so on, I think we should definitely play its strength: connection to multiple networks, especially now that Microsoft removed the half connection limit on Windows. As for the UPnP, the advantage is obvious: if it works, great, if it doesn't, nobody loses anything. This is what LimeWire does AFAIK.
There may well be downsides to such a configuration by default, but I fail to see what these could be, so your opinion is more than welcome.
