It would be very convenient to have this feature.
We could implement in a similar fashion to the CartoDB implementation:

@capooti
this feature to upload layers right?

[capooti]

@mishravikas yes, to import vector/raster layers. In some use case it may be more convenient

[mishravikas]

ok I would like to work on it

[capooti]

Excellent. Looking forward to it then :)
Ping me on IRC for details

[simod]

[garnertb]

Yes, I think so. I'll update it for now.
