Hi All New to forums and wandered if you could help??

Just purchased an FZ100 and am looking to conduct interviews for a website, i am wanting to attach 2 tie clip style mics so both the interviewee and i can be clearly recorded. Is this possible can i have 2 mics off one input and can i use any 2.5mm mics setup eg......................... http://www.amazon.com/Cable-Store-Stereo-Headphone-Extension/dp/B000Z0YECU/ref=sr_1_1?s=electronics&ie=UTF8&qid=1296252325&sr=1-1 / http://www.amazon.com/Belkin-F8V234AMOB-6-Inch-Audio-Cable/dp/B000BFFXQU/ref=sr_1_26?ie=UTF8&qid=1296251776&sr=8-26 / http://www.amazon.com/Sony-ECM-CS10-Business-Stereo-Microphone/dp/B0049PGCR2/ref=sr_1_6?ie=UTF8&s=electronics&qid=1296251921&sr=1-6 something like this
