Just posting status. Mostly harmless:
mono at home(4M/512), two at work(5M/5M), an old 1.11 at Another 
Network(32M/32M). I have two IPSEC tunnels to work, three to Another, and 
one to a friend's network. Lots of rules.
Everything is smooth, and the C3-800 boxes I use show <15% cpu, as usual, 
and getting ~440k/sec from work. They top out at around 75Mbps/70%, as 
usual, due to the RT8100 NICs used.
There was some bumpiness with connections being lost when I fetched gigantic 
files from the company HTTP server, and that winbox in turn had to fetch it 
through SMB from my Linux box at work, but, a ms-operation (reboot) of the 
webserver apparently made that go away.

Q:
The one thing that puzzles me is this: mono (1.3b2) now recognizes an 
ural(4) nic (since Manuel Kasper mentioned ral(4), I thought I'd try it) and 
reads the MAC address correctly, only how does one configure such a thing 
(it's not recognized as a wireless device?)?

Feature idea:
When the user asks to upgrade with an 8MB card, redirect to a "Last time you 
did this, you had to drive halfway across town, climb up the mast, and 
replace the CF card. And it's probably raining. Do you really wish to get 
wet?" I was SO certain it was a 16M card.
