the garden distribution is a subset of tex live plus some extras and 
users can choose to install additional modules and fonts (which will be 
remembered when as next update happens) ... we could add dll/so to that 
is needed (which then will be compiled along with the luatex binaries so 
there is a consistent set)

well, i only provide the standard context files to tex live so if users 
put some other stuff for context in it that is fine for me; but the 
problem is not so much extra libraries but more to make sure they don't 
mess up regular usage; it's not different from adding additional node 
juggling code: it can (and probably will) interfere with core 
functionality and as such is not officially supported (or garanteed to 
work with updated context kernels); for instance, an alternative font 
handler or input file (location) handler is very unlikely to work, 
although the later is easier to plug into the framework)

i suppose so

i dunno

context has its own loading mechanism (and sandboxing model) so if there 
is demand i can add or lift all kind of restrictions via the 
configuration file
