At this point, I'm thinking about 3 solutions for the server solution:
- Reuse my old Toshiba Libretto 70CT: I realy like this awesome tiny machine but I dont use it any more. It's a true laptop with a Pentium processor running Windows 95. I Only need to find a 16 bits PCMCIA network interface but I'm not sure it can fit in a Teapot.
- Buying an Raspberry Pi. This fashion card seems to be supported by a big community. I'm sure it can be a good, and more modern solution, but it's still difficult to find those cards.
- Building an OpenWRT solution based on an TP-LINK router like the MR3020 or the MR11U. Cheap, easy to find and supported by the community of PirateBoxes projects.
