Adding styles and/or pages to the web GUI?

[BL]

Is it possible to add anything to the Access Server web interface?

There are broadly two sets of things we'd like to accomplish:

1. Changing how the user-facing interface looks to bring it in line with a company style. The most important parts should be achievable by just adding some additional CSS. Is it possible to add inline CSS anywhere, or link to a stylesheet on the server?

2. Adding something to the admin part which can send signals or commands to the server. We have administrators who have access to the web interface, but will not be SSHing into the server. We'd like to provide something to allow them to perform tasks like unlocking users from the web interface. It doesn't really matter whether that directly hooks in to the AS software, or just sends something to the server which in turn gets picked up by some service or cronjob we provide which then executes commands. Is something like this possible?

We've tried searching the AS documentation, but haven't been able to find anything.
For #1 we've been able to add the client's company logo, but that's pretty much it.

Any help would be greatly appreciated.
