If I had my choice of languages to use for remote execution I would pick TURING.
TURING is a full and simple to use programming language that has a number of
features would make it ideally suited to use as an agent scripting language.
1) Turing has a formal and provable semantics(this includes IO) and
claims to meet the US DOD criteria as a TRUSTED language.
2) both compilers and interpreters exist for Turing.
3) Turing supports `faithful execution`; this means that either a program is
executed according to the language semantics or else it is halted with a
message describing the nature of the failure.

I would argue that the agent is not as important as who's agent is it.
If you give a person access to your system then what is wrong with giving
their agent the same access. In this way all of the standard security rules
that apply to normal users should apply to their agents. The main issue that
I can see is that a reliable way to verify who this agent belongs to, needs to
be developed. A second issue would be insuring that the language/protocol
that is used by agents is reliable and verifiable.
What ever ends up becoming a standard for allowing agent execution it should
be reliable and stringently checked. If the current trend in software
development is used then the internet worm and other virus incidents will pale
in comparison to what will happen.
