Remote publish of infopath to wss site

[Zaflap]

Hello all,

I have a .net managed code behind infopath form which is submitted to a
document library on wss (meaning i have a promotion of columns etc.) .

which componnents can i remote install (the server is behind firewall
in the customer site).
1. i guess the publish it self can not be done remotly ...?
2. can i just update the code behind dll remotly ?

Thanks.
