site hosting on 2 internet connections

[Jacob Yocom-Piatt]

just got a 2nd connection with a better upload capacity and would like 
to use both connections to host a site i run. everything is currently 
served over a single connection that supplies netblock a.b.c.d/29 and 
terminates at the firewall.

i plan on connecting the 2nd connection that supplies netblock 
w.x.y.z/29 to the same firewall and, unless someone can point me towards 
a better option, changing the DNS for the site to point to an IP in the 
new netblock. if there are any "gotchas" about such a setup, please 
point me towards the relevant docs.

i've read about using the route-to to balance outbound connections in 
the pf address pools docs, but i don't see this being immediately 
helpful for hosting purposes since the inbound connections should come 
in on both netblocks in the case that the load is spread over the two 
connections.

cheers,
jake
