Answer 1

Which client extension support muc/mucLight protocol ?

MUC is supported by almost every client library, MUC Light is supported by Smack and XMPPFramework. Also, MUC Light may be configured to use MUC protocol (with some MUC Light-exclusive features unavailable).

Is there a way to have a shared history for a group using muc/mucLight protocol ?

In MongooseIM both MUC and MUC Light use the same extension and table for archiving so theoretically their archives should be compatible but it is not a requirement so is not tested automatically in the project.

Which is improved for mobile devices ?

MUC Light exchanges data much less frequently than MUC and the packets attempt to carry information as efficiently as possible to reduce round-trips and unnecessary traffic.

any others pros and cons ?

Here are the high-level principles behind MUC Light, that more or less directly indicate differences.
