Agile Scrum – Can Daily Scrum Meeting Be Replaced by Status Email?

You're describing managerial dictatorship, not agile. Agile is about incremental development in a field of changing requirements, not about dictating people how they individually go about doing their work.

One common problems in Scrum is that sometimes you'll get a Procrustean manager who wants to do things "by the book". They forget that the goal of using Agile/Scrum isn't to do Agile/Scrum but to deliver better quality and more user responsive software in an iterative fashion. You also get a lot of "Scrum In Name Only" managers who think that having a short daily meeting is all there is to Scrum. It can also become an enabler for micro-management prone managers.

In your situation, I think you and the Scrum masters in the various groups should be able to determine if you're needed for a stand-up on a particular day. For example, if the team is currently working on sprint that doesn't involve you directly, such as working on object models and the database, then you don't need to be there.

Given that you're providing work for multiple teams, you're more like a vendor, an ancillary role, rather than a development team member, a core role. That may be the way to approach it if your management is too by the book. If you're working alone, you may end up solo scrumming on your sprints. There was a good discussion of doing a solo scrum in this thread.
