[9fans] acme under plan9port : made to work?

[Mayuresh Kathe]

i apologise up-front for asking this on 9fans, but, how is acme and 
plumber and all it's utilities (including upas) made to work under 
non-plan9 systems via plan9port; on say something like linux or even mac 
os x?

do they have some kind of user-level library which emulates 9p?
