Hi
Checked for the SSHd on the elonex, not installed, which means it needs to be cross compiled for mips, and then installed.
BUT, imho, you don't really need it, unless you want to access the elonex acroos a network that goes outside your router, ie out of your private network. Of course, the onet+ could become a great remote situation quick install monitoring machine, and then you would have to do more secure stuff, but for playing, its not really worth taking up the space.
