Not great, IMHO. Not impossible, but not great. Cisco was / is the only
major vendor that has really paid attention to multicast closely across
the last decade, and their experience shows (especially in the
financial services community). As you design your network, be
particularly careful of the results of route convergence and the timer
sets behind MSDP (if you're using) and its configuration. You can get
"blackout" periods of 60-75 seconds or even longer off of a route
convergence where the multicast packets won't flood until the timers
catch up with the convergence.

Just verify your design in the lab with sufficient "negative testing"
breaking your routing protocols and seeing how long it takes the tree
to heal.

There's quite a list of issues here desire-able to mention, this is
certainly not the only one! Just the one that came to mind when I read
your post.
