Maintain adhoc network connection when connecting to BT DUN?

Is there a script that will maintain an active ad-hoc connection while I initiate a bluetooth DUN link to my phone?

Gameplan-

a) create an ad-hoc connection for n800 and 770 (or laptop) with static IPs

ON N800:
b) connect bluetooth DUN from n800 to phone

c) echo 1 > /proc/sys/net/ipv4/ip_forward

d) route add default gw <nokia.n800.ip.address> dev <nokia.770.ip.address>

Goal-

Use my unlimited data plan with my n800 and then share it with my 770 through an ad-hoc wlan link.

Thanks!!!

I was partially able to resolve my problems, however I never got it completely running (was on holiday there, didn't want to spend ALL my time with the gadgets...) on my N810. I'm posting my first steps to the solution, perhaps it might help someone else or a linux crack can chime in and explain:
The Hotel uses IACbox (rebranded as Siemens Internet for Guests), which is a Linux-based access control system. The IACbox support FAQ mentions that some Linux distros (evidently Maemo being one of them) are unable to "set a hostroute if multiple network cards are in use" (???). In then points out that to resolve this, one needs to act as "root" (gainroot, becomeroot, sudo whatever, I did ssh to localhost...) and then add an additional route/gw (172.30.3.254/32).
I took these instructions and "translated" them to Maemo, resulting in something like:

Code:

route add default wlan0

route add -net 172.30.3.254 netmask 255.255.255.255 wlan0

route add default gw 172.30.3.254

After this, I was able to finally access the login page of the system and authenticate myself (each Guest gets a user/pw that is valid for the duration of his stay).
Unfortunately, I was still only able to access the unprotected "free" sites, as something with the redirection didn't seem to work (I got some "out of memory / not enough memory for this operation to complete" errors from MicroB, perhaps a javascript issue).

My questions:

Why are many distros unable to do this? (Rant: Is Linux still not ready for the desktop and mobile environments? OSX and Windows do work properly...)
Shall I file this on the Maemo Bugzilla?
Anybody with an idea about the error in MicroB?

A script to connect to adhoc while maintaining BT DUN would work as well.
