Daniel Boyd, his sons, Dylan and Zakariya, and four other suspects - Anes Subasic, Hysen Sherifi, Mohammad Hassan and Ziyad Yaghi - are all charged with conspiracy.
Authorities say their operation was being run from a home in Johnston County.
The FBI has said that it seized some two dozen weapons from the Boyd household and that a pit had been dug under their back deck to be used to store the guns.
They also seized more than 27,000 rounds of ammunition, along with $14,000 in cash.
The trial is set for next year, but the case has bogged down over the translation of 750 hours of FBI surveillance tapes and 30,000 pages of documents.
Now, defense attorneys want to take their case overseas, to the Middle East.
"Mr. Yaghi has always contended that his 2006 trip to Jordan had nothing to do with violent jihad," said defense attorney Doug McCollough.
But prosecutors claim the 21-year-old took a trip to Jordan to plan a violent terrorist act.
Yaghi says he went to the Middle East simply looking for a girl to marry.
"We have witnesses who can corroborate that, in Jordan, his purpose was to go and meet a suitable bride," said McCollough.
The U.S. Attorney wants all seven defendants in one trial in September of 2011. At least one defendant wants his own separate trial. Another defendant has fired his lawyer after one year. So, the legal wrangling will only continue.
