You can use multihead setups during meantime until wmii-4 in October.

Showing different tags on a Xinerama multiscreen won't work,
because a client can only be visible in one position at a time.
If I have two 1600x1200 screens and a client tagged 1+2 it is
technically impossible to display it on both Xinerama screens at
the same time.

I think that Xinerama support needs the refactoring of Area. In
particular, we need to replace area with something like:

- Floating area struct (Xinerama display wide)
- Column layout struct (Xinerama screen related)
- Column

Each View contains 1 floating area struct, and n (=number of
screens) column layout structs. On column layout boundaries we
will populate a move to the other screen.

I think this is the most simple approach which only needs very
small changes and scales well up to more displays (however, I
only expect to support line-based Xinerama setups, matrix based
will not be supported.
