Even if you have one good luck with static ip. If you have a dynamic ip address then it will keep changing on you.
I myself am looking at remote log in to monitor and this NTMT sounds intriguing albeit not very intuitive to look at. I am running strategy on my home pc.
I was more thinking in the line of installing software such as logmein or gotomypc which would then enable a smartphone to do its magic.
I started looking into smartphones and found that windows mobile 6.5 can be found on samsung omnia II and HTC Imagio while 6.1 can be found on HTC Touch Pro 2. All of it is useless if you cant use rdp client. Way to go Microsoft.. If they cant lock a user like me down, then good luck with those using iPhone OS and Android OS. So no winmo for me.. besides logmein doesnt work on it either I believe.. I maybe wrong on that..
If you go for android phones such as Moto Droid, then you can download an app such as phonemypc which last I checked was in beta and had ssl turned off (and your pc had to be unlocked)
Nexus One has android 2.01 but not sure about its app availability.
iPhone has logmein ignition but I am into verizon so no iPhone for me thank you. All the above mentioned are from VZ.
You can zoom in and out on any of these phones so 3.6 inch screen is not a problem while remote logged in.
Worst part about these expensive smart phones is that they turn instantly into paper weight as soon as you end your contract. Except for global phones which might work on other carriers but only at 2g speeds. 3g frequencies vary per carrier (Tmo 1700, ATT 850 / 1900 mhz). Only TP2 comes with North American 3g on both cdma and gsm but it is software locked from using other carriers on 3g. Imagio has 2100 mhz single band 3g that will work only in europe.
Here are a few links.
