This is actually more a feature request than anything else.
It would be nice if the client installer would be absolutely
zero entry level so that the hurdle to install Limelight for the
common user (your sister, aunt, etc) would be lowered
completely.
Currently the client installer requires Java to be installed in
the system beforehand. There are many people who don't really know
how to install this things (one of the reasons Java didn't really
make it into the desktop; apart from the UI libs ;) ).
If the client installer would install Java in the system (if not
present) it would improve drastically the acceptance of it as less
technical savvy people could install the client and be up and
running without any requirement apart form having a computer...
Cheers!
