Interesting. I'm able to make instant transfers within the UK (also on weekends) and I believe throughout Europe. There is still the issue of other currencies but I believe the original discussion was about sending money to other people within the same country (the US) so our system surpasses the criteria as it works between around 30 different countries.
In Portugal, between same bank takes a few seconds, between different banks, usually next day (sometimes same day, but not common from what I have seen). I just sent some money to Germany and took a day to arrive in their bank account. On the other hand, I received a bank transfer today from the USA which was issued on Tuesday (2 work days, which is not bad)
