[strongSwan] Strongswan equivalent of openvpn push-peer-info

[flyingrhino]

Hi,

Do we have an equivalent of the --push-peer-info command that openvpn 
has?
Of most interest to me is the initiator pushing environment values to 
the responder when it connects so that I can program the up/down script 
to act upon this information.

Here are the useful bits from the openvpn man page:
  Push additional information about the client to server.
  UV_<name>=<value> -- client environment variables whose names start 
with "UV_"

Thanks.
