this is just a thought that posting via sms/mms is possible.
but, i dont know anything on programming….
so… just find some programmer try to translate this into php…
– have one mobile phone with sms/mms capability
– have it connected to your computer by usb/serial cable or irda/bluetooth
– have a program on your pc (that’s connected to internet) to ‘suck’ whatever come in to your phone in sms/mms
– have that program to upload the content to your blog via xmlrpc.
