I'm using R on my tablet by connecting to an online server with RStudio
server  http://www.rstudio.com/ide/server/ and I'm wondering if a similar
solution would be feasible for gretl?

I've thought (to a limited extent) about this sort of thing, and I
came to the conclusion that there's nothing useful to be done right
now.

A determined geek could get gretlcli running on just about any
modern device (from raspberry pi on up, and including ARM). But the
GUI is another matter, for two reasons: (1) gtk is not available for
(and/or would not be permitted on) the devices one might want to
target, and (2) even if gtk were available, gretl's desktop-type
interface is just not right for use on tablet / smartphone / toaster
/ whatever.

My motivation to write a touch GUI for gretl in Java or iOS is zero
but if anyone else wants to try I'll be happy to make encouraging
noises and help from time to time, to the extent I can.
