Colin -
There are no system manager capabilities to create roles from. However there are API capabilities to create roles. The capability would be for the API, file-read-file, which allows the user to read any file given a path. If a role was created that only allowed http login and file-read-file, I can imagine System Manager would not do well. System Manager 1.x was not designed to interogate roles.
If you want a syslog reader, I reccommend creating a program that uses file-read-file to obtain syslog information.
