*raises hand*

The company I work for now has different PHYSICAL networks for "inside" and "outside". "Inside" network has the SMS sending daemons (we send reminders of expiry to users who want), and the interface to add, mode and delete.

There are no bridges. There are only two PCs that have access to both networks, via separate NICs, and both reside in the IT dept (one is mine), and there is no routing.

There are firewalls, no sharing (except via mounting the file server's), per-user and per-department permissions.

There is no log-in service, but if there were, I'd use a hash to logon. There's be a PC that only has a *custom* service port open through a physical firewall and I'd put the phone number server to periodically send a hash of the numbers to the login server. The login server gets the number from the user, hashes it, and compares it to the available hashes. That way, a hacked server only publishes a list of hashes that can't be unhashed. Unlikely hash matches (shouldn't happen) are distinct by passwords.

And all I'd have to do is buy a firewall and a silly daemon that hashes a list of numbers and sends it. 500-800$?

Also, communications with Nokia, which embeds support for good measure.

No and no. Those make my phone worth keeping. Also, it doesn't actually crawl to an unusable mess. It's just that memory starts to be swapped and when I unlock the phone and start apps it swaps and swaps, less responsive. If I keep using it it will eventually swap enough to return to usable, it's just that it takes less to reboot than to wait for swapping.

Also, if it's swapping, the something leaked. Sooner or later ...

Bottom line is, it's not unusable after 4 days. It's just visibly slower.
