If you have a console where the channels can be switched off and on remotely you can use an external relay board to do your feed switching, instead of the Broadcast Tools switcher.
I have an AC station, with the main programming from Dial Global. However, we air Delilah at night (Premiere Radio) and two shows from Tom Kent on the weekends (Citadel/Cumulus satellite). On top of that we take a 1 minute cast from Fox News at the top of the hour (off the Premiere XDS) ; and a weekly sports scoreboard show from a regional news network (Comstream receiver). Five dedicated faders, in case you've lost count.
Simian will also support the Broadcast Tools 32 input trigger board, (the normal device they sell, from Measurement Computing, supports 24 trigger lines). With the music networks I need all these different trigger inputs since the net-cues are coming from four different receivers, and the music shows use a number of extra triggers for liners and drop-ins.
As I mention above, if the ESPN station becomes successful (and I wish them all the luck) they'll want to add other feeds from live broadcasts of pro and college teams in your area. Major college football and basketball can be a sure moneymaker--years ago I owned part of a company that networked Ohio State basketball.
I still have a Starguide in use--for the Steelers. But that's on the classic rock station, and, since they don't "tone" the game day broadcasts, I use a live operator.
