Maybe one day.
libavg which the client runs on don't officially support builds on ARM so that would need to be solved first. Then also Chromium and Berkelium and libbrowsernode would all need to be ported too.
Once that happens, the bits of the client we actually write (in Python) should run OK without many/any modification.
I suspect though that it will turn out to be too underpowered though - but I'd love to be proven wrong.
If someone wants to take on getting an ARM port underway then feel free to contact me - and I'll help where I can - but I don't have the time or resources to undertake it at present myself.
