At work we have recently started testing a web-based trading platform for swaps. After pointing the browser to the respective URL you enter the relevant data (effective date, notional, currency, &c) and klick on "request for quote". The system will take a little time to process the data and price the swap; and you have about 7 seconds to accept (and immediately enter a contract) or reject the quote by klicking on the respective button on the popup.
I have often used his platform to get tradeable price-*indications* until recently when I had the chance to take a look at the inner workings. We had some technical problem with the systems and contacted the support. They passed us on to the trader, a person who has to _manually_ release any quote before it is sent out. D'oh!
