Hacking a router would certainly be interesting and fun but as far as usefulness onboard goes seems very limited compared to what else is available.
Agreed but there is a little catch
Raspberry Pi is an amazing little device with a lot of power and a great OS. However, there are also advantages of more 'embedded like' systems.
Not all but most of them run OpenWrt, a Linux
distro targeted for embedded devices. OpenWrt is a really great router operating system. One particular advantage would be to make it an onboard wireless hub with Internet
Pi can act as a hub as well with Internet
sharing and such, but only in ad-hoc mode due to chipset limitations. Some of the router boards by definition will be AP quality and they can still do AIS
, kplex multiplexing etc (but you wouldn't want to do OpenCPN
;-) ). There is another little box called Carambola2
which is based on Atheros AR9331 SoC, which costs some $25. It makes a perfect WiFi
router (AR9331 is essentially a popular chipset for now low-end routers and APs) running OpenWrt.
I have been thinking of combining Adrian's dAISy with a Carambola2 to make an embedded router/multiplexer but that is more of a longer term fun project
than anything else.
Anyways, probably went on a long tangent but I could not resist
