	Actually, what seems missing from the diaplan apps is one that just
writes to the Manager API socket any passed string, and one to read from
the Manager API socket any sent data. The read command would be even
better if it could be connected to the API initially, and buffer data
sent from the Manager, for parsing by regexp (and flushing). These apps
would be especially useful in Perl Asterisk::AGI. That way dialplan and
Perl (etc) could always offer a consistent API even with arbitrary added
apps to the local installation.

ManagerWrite(<command>, <delimited-data-string>)
ManagerRead($[<channel-variable])
ManagerSubscribe($[channel-variable])

	Right now it looks like the only way to do it is to write a Perl sub()
in each Asterisk::AGI Perl script that opens a socket and reads from it.
And maybe update the local install's pm. Much better if it's
standardized as part of the API that everyone's AGIs (or diaplans) can
call, depending on the installed Manager commands installed.
