its not joking... seen some rally racer doing it all the time. and its pretty easy when you at right rpm/speed. but I never done it with my Evo 8 .. used to do it with other cars but just dont wanna do it with my Evo 8 coz Evo's transfercase and clutch isnt that strong ..
and about shifting with out clutch.. its just like slide in. shouldnt have any resistant at all ...

no, it's quite possible to shift without using the clutch. Downshifting is typically quicker since you ahve the capabilities to rev match. If you're good, you would only need to pause in between gears for a split second. Upshifting is the harder part, you either have to wait for the revs to drop, or put stress on the synchros. But, both can be done safely.
On a side note, clutchless shifting is precisely how the corvette test drivers rip out the record setting runs. And motorcycle racers will often shift clutchless (sometimes timing it with fuel cut to slip into the next gear....so cool!)

If your planning on having your tranny last I would not do. Unless your amazing a rev matching it will most likely wear your syncros alot faster then normal.

ha its not really that bad for your tranny, i wouldn't do it constantly, but the car will easily slip into gear at certain rpms. again, i wouldn't do it daily, but if you do it right your not destroying anything.

Umm..the rally racer you're talking about was probably using anti-lag to keep the turbo spooled between shifts as well as NTLS (no lift to shift) for even shifting at high rpms to minimize off-peak power. NTLS is computer based through an EMS system as is anti-lag.
In answer to your question, flatshifting is hard on your clutch as well as driveline. It's not recommended by most unless you use the aforementioned idealogies with NTLS built into an EMS *and even then there have been multiple people who've broken parts whilst performing such stunts.*
HTH.
