The next one (AFAIK) should work on every OS:
\startluacode
local user = ""
local users = {
["ousia"] = 1,

function document.CheckUser()
user = os.resultof("echo ousia")
context.verbatim(user)
end
function document.UserNumber(name)
context.verbatim(users[name or user] or 0)
end
\stopluacode
\def\CheckUser {\ctxlua{document.CheckUser ()}}
\def\UserNumber{\ctxlua{document.UserNumber()}}
\starttext
This is user \CheckUser with number \UserNumber.
\stoptext
(Untested)
Change `local user` by
~~~
userdata = userdata or {}
userdata.user = ""
~~~
and all other occurances of `user` by `userdata.user`.
