Are templates not available yet?

We now support a writable filesystem, but it seems that the sheer size of the Meteor installation makes it unusable in Gomix at this time.

Does it possible to use meteor?

Not really, sadly. The filesystem does help, but the installer is larger than the space you have on Gomix (it bundles Mongo and all sorts of other stuff) and it requires command line access to use.
