(Not so) Easy.
I'm no physicist - as Mr Roberts my Physics teacher many years ago would confirm - so I don't know whether it's possible for waves other than sound waves to travel down the line from one studio in London to the other in Cardiff.
But early this rmorning as I sat at the Cardiff end listening to two MPs, Hywel Francis and Wayne David, being asked about yesterday's meeting with Rhodri Morgan, their lack of enthusiasm seemed to roll down the line in great waves.
The mood, said Wayne David, was 'sombre'. It's pretty clear that any deal Labour strikes on holding a referendum on full powers for the Assembly will include a get-out clause of one kind or other.
"Why on earth would we bind ourselves to a timetable on holding a referendum and then find there was no appetite for one, lose the vote and miss out for another generation?" That was the tenor of the conversations I had yesterday.
A ring-around of constituency Chairs today (and more on that to come) suggests so far that the majority could just about stomach the inedible deal if they had to ... unless the unpalatable scrapes itself from the floor and puts itself back on the menu of course. Surely one course too many even to contemplate. Surely?
More from Rhodri Morgan tonight who's being interviewed on Dragon's Eye. Tune in.
Good news for one Welsh MP at least. Martyn Jones has won his libel case against the Mail on Sunday and is £5000 richer. He could afford to buy a full-length tie with that ... and good news too for the Poltical Unit 5-aside football team who last night beat Plaid Cymru 12-7.
(Not so sure they could have taken Plaid/Labour coalition mind ...)
Lib Dems then Labour up next week and the challenge has gone out to the Tories.
And no, it's not true that Plaid called a special conference before they decided who was in goal.
