I think this would be a nice feature for pyplugins developers.

In this moment the only workaround to make a layer uneditable is creating a
plugin window containing a new canvas, then adding the layer in this new
canvas,
but you can neither use useful tools (e.g all the newest selection tools) or
qgis
mainwindow capabilities (add layers, move layers, ...).

I'm going to open a ticket on trac.

Cheers.
